so yeah, stupid topic but i just received my 4220 from laptop authority who were fantastic to deal with. It is now sitting here infront of me and the document says to plug it into the a/c before powering up, i assume to start charging. Is it as easy as just buying a US adaptor for the AC, plug it into the Aussie socket and away i go? It also says to register vista. i am inclined to do so. do i have to? And what is this "Click Me" that i have to install also? cheers.
